Question

A swimming pool is 30 feet wide and 50 feet long. If it is surrounded by square tiles, each of which is 1 foot by 1 foot, how many tiles are there surrounding the pool?

Answer 1

164 tiles

Explanation:

Per the above details, we will require tiles along all the sides of the swimming pool ,hence the circumference of the pool is denoted as;

= 2(wide + long)

Wide = 30 feet

Long = 50 feet

Circumference = 2(30 + 50)

Circumference = 2(80)

Circumference = 160.

It means that minimum of 160 tiles of 1 ft length is required, however, we will also require tile on each of the corners(4), total equals

= 160 + 4

= 164 tiles

A total of 164 tiles are there surrounding the pool.
